BINDING PERFOHATED LOOSE SHEETS Application filed September 29, 192 Serial no. 188,373.

This invention relates to the binding-of perforated loose sheets between a pair of cover sections having perforations to register with the pcrforationsin the sheets for the engagement of fasteners, and it is theobject of the invention. to provide improved binding means comprising a strip of pliable and readily severable metal foldedupon itself to form a head at the fold with two parallelly extending portions or tongues the free ends of which are arranged toextend' beyond one of the covers, and to provide locking means to engage the free strips comprising a blank of pliable inetal arranged tobe engagedupon and inter-folded with the free ends of the fasteners.

Another object of the invention is to pro vide a fastener or hinder of pliable and readily severable material to adapt the 'fas tener for the binding of stacks of sheets of variable thicknesses, r

Figure 16 is a perspective view ofa perforated hinge plate with thebinder inserted.

In the embodiment of the invention a stack of sheets having perforations 17 adjacent one of the side edges and havinga slit 18 communicating therewith cut through the edge of the sheet are bounded by av pair of cover members 19, 20 having a strip fiex iblyconne'eted thereto at one edgeias at 21,

to lie contiguoustothe inner, surface of the sheets over whi'clrthe cover inei'nbers are adapted to beiolded and to act as ahinge for said covers. The strips 21 are arranged with perforations 22 spaced'to register with the sheet perforations. The cover members are placed at the top andbottoin of'a stack ofsheets with the perforationsof the hinge strip placed. in register with the" perforations in the sheets. Fasteners are then passed through the perforations, comprising a strip of flatlaterally pliable edgewise stiff and readily severable metal bent u Jon itself in such anianner, as shown in igure 5, tolforni a head 23 adapted to abut against the hinge strip of a cover, the lower cover 20 in the present instance, and parallellv extending portions or tongues 24: with the free ends thereof extending beyond the hinge strip '21 of the upper cover-l9 when the cover isin open position asshown in Figures 3 and i. 'IhefziSteriers are engaged inthe perforations of the sheet body with the width thereof to extend: parallel to the edge of the sheets whereby the fasteners,

' due to tliefiexibility of the metal. will readily adapt theniselvesto conform to the cur vatu re ofthe sheetsas the bound sheets are length than breadthis provided with a per- 'loration -26 arrangedlengthwise of the plate and corresponding in shape with and of a lit size substantially the same as the cross sectional area of the tongues 24 of the fastener and with the ends 27,27 reduced in width and bent at right angles to the body portion of the plate. This plate is engaged over the free ends of the fastener as shown in Figures 3 and 4. It will be noted that the free ends of the fasteners may be of a length to extend for some length above the plates 25 whereby they are adapted to the binding of stacks of sheets or sheet body of different thicknesses. In the arrangement as shown in Figures 3 and 4with the free ends ex tended for a, considerable length above the sheets a predetermined portion is severed therefrom, as on the dotted line 24 (Figure this length depending upon the width of the tongues of the fasteners and the length of the plates 25 between. the angle portions 27, 27. The fasteners as stated are made of thin and severable metal, such as brass, which may be readily cut by a pair of shears. The plate 25 is then engaged upon said projecting end of the fastener as shown in Figure 7, or it may be engaged thereon before the fastener is severed, when the free ends of the fastener tongues are spread and bent flat against the plate be tween the bent ends 27, 27 as shown at 24 in Figure 8. One of the ends of the plate 25, such as 27, is then bent over and against the surface of the spread fastener ends as shown in Figure 9. One of the spread fastener ends 24 is then bent backwards upon itself over the bent end 27 of plate 25, as shown at 24 in Figure 10, when the other end 24 is bent backwards upon itself over the bent end 24. The plate end 27 is then bent over the interfolded ends as shown in Figure 11 when the same may be struck with an implement, such as a hammer, to flatten the same.

In the modified form. of binder shown in Figures 12 to 16 the two covers 19, 20 are pivotally or hingedly connected to a back 28 by arranging spaced rolled portions 29, in the nature of binge knuckles, along the opposite longitudinal edges of the back for the engagement of a pintle wire 30. The covers have hinged members 31 mounted along an edge arranged to engage the spaces between the knuckles 29 of a length less than said spaces to be engaged by the pintle wire 30. The sheets are bound by means of the hinders or fasteners 24, and to unite the cover with the sheets perforated plates 32 (Figure 16) are provided, these plates being arranged with an eye or knuckle 33 for engagement on one of the pintles 30 in juxtaposed relation to the hinge member 31 to lie contiguous to and have movement on the pintle independent of a cover member, in the present instance the cover member 20. The plates are arranged in interposed relation between a cover member and a stack of sheets engaged between the covers with the perforations therein in registrathin with a perforation in the stack of sheets, the hinder or fastener 24 being passed through the plate perforation with the head 23 in abutting relation thereto. Securing plates 25 (Figure 15) are provided similar to the plates 25 with the exception that they are formed with an eye or knuckle 34 at one longitudinal edge whereby they are 1nountedupon the pintle wire 30 for connecting the other cover member 19 to the back to have inot'ement on the pintle independent of the cover member. These plates are arranged to lie contiguous to the inner surface of the cover 19 in interposed relation to said cover and the upper surface of the stack of sheets, as shown in dotted lines in Figure 12. The plates have a perforation 26' for the pussage of the ends of the tongue portions of the fasteners extending beyond the top of the stack of sheets and extended portions 27, 27 for interfolding with the ends of the fastener tongues in a manner similar to that described in connection with Figures 7 to 11. It will be obvious that by this arrangement a fiat opening back arrangement of binder is provided and adapted for use as a check book, order book and the like by the binding of blank checks or order blanks between the cover members 19, 20.

Having thus described my invention, I claim:

8. Means for the binding of perforated sheets into a sheet body, comprising a flat strip of laterally pliable and edgewise stiff and readily severable metal folded upon it self with the ends to-eXtend in parallel relation and arranged at the foldwith an abutment, said strip being engaged in the perforations of the sheets with the width of the strip extending parallel to the binding edge of the sheets, and a perforated plate of pliable material engaged upon the free ends of the strip and interfolded with the end portions of the strip.

4t. In means for binding perforated loose sheets into a sheet body, a strip of pliable material folded upon itself and arranged at the fold with an abutment engaged in the perforations of the sheets with the width of the strip extending parallel to the binding edge of the sheets with a perforated plate engaged on and interposed between the abutment and sheet body, and a perforated plate 7 arranged at the ends with flap portions engaged upon the free ends of the strip and the flap portions interfolded with the end portions of the strip, said perforated plates bein arran 'ed with an e e at a inar 'inal n a: I r:
